JEE Main · PhysicsEasy
In an intrinsic semiconductor at room temperature, the number of electrons $n_e$ and holes $n_h$ are related as
- A.$n_e > n_h$
- B.$n_e < n_h$
- C.$n_e = n_h$
- D.$n_e \times n_h = 0$
Show correct answer & step-by-step solution
Correct answer: C — $n_e = n_h$
Solution
In an intrinsic semiconductor, charge carriers are generated only due to thermal excitation. Since each electron-hole pair is created simultaneously, the concentration of electrons equals the concentration of holes .
